Owens Lake Clay, Plio-Pleistocene, Inyo County; pharyngeal arch and teeth (fig. 2i) and Weberian 
apparatus (fig. 2j) [UMMP 50905-50906]. 
From Keeler South: Owens Lake Sand, mid-Pliocene, Inyo County; posterior maxilla (fig. 2a), anterior 
maxilla (fig. 2b), urohyal (fig. 2f) and Weberian rib (fig. 2k) [50895-50898]. 
Remarks : Smith et al. (2009:179-180) in the text describe specimens UMMP 50895-50898 and 50905-50906 
as though they are either f Catostomus fumeiventris and f C. tahoensis, but in the legend of figure 2 they 
identify the specimens only as f Catostomus sp. 
Genus Chasmistes Jordan 1878 
Chasmistes cf. C. cujus Cope 1883: Taylor and Smith 1981:350, pi. 19, figs. 9, 10 
Referred Specimens : From Honey Lake, upper Alturas Formation, mid-Pliocene, Lassen County; Locality A: 
one maxilla (no specimen number or figure); Locality B: UMMP V74462, right opercle (fig. 9) and 
UMMP V74461, left hyomandibular (fig. 10) and several other skull bones without catalogue numbers or 
figures. The figure legend of plate 19 identifies UMMP V74461 and V74462 as Chasmistes sp. not 
Chasmistes cf. C. cujus.

Pliocene, Modoc County; no individual specimens were listed, but the specimens were deposited at UCMP 
and their catalog lists specimens 143065-143072 as catostomids (see entry above for Wagner et al. under 
Catostomus sp.). 
Referred Specimens in Smith et al. (20021 : From Mono Basin, formation not given, Late Pliocene, Mono 
County; no specific specimen mentioned. The authors make general statements that the skull, maxil¬ 
lae and dentaries compare favorably in part to fC. batrachops Cope 1883 from Fossil Lake, Oregon 
and Snake River Plain, and to the specimens from Secret Valley, Lassen County. 
From Honey Lake “Island”, upper Alturas Formation, mid-Pliocene, Lassen County; no specific specimen 
mentioned. The authors state that Honey Lake specimens are intermediate between C. cujus of the 
Lahontan Basin system and C. spatulifer Miller and Smith 1967 of the Snake River Plain. 
Remarks : Smith et al. (2002:215) identified the specimens from the Mono Basin as f Chasmistes sp. undeter¬ 
mined. According to K. Gobalet (pers. comm., May 3, 2010), the specimens of f Chasmistes sp. studied 
by Smith et al. (2002) included 39 partial dentaries, nine maxillary fragments, one palatine, one ethmoid,
